delta ratio

[juanfer]

Hello, I am trying to convert this indicator from tradestation to ninja.
Two questions I have are as follows, the rest of the code I think I will I get program it.
1 as was desiganan to variables in the code are as intrabar persist.
This type of variables will be updating with bar without closing.
2. the second is that function returns insideask and insidebid, which are the best price at which are the bid and the ask and tradestation are snapshot.
Thank you




inputs:
Period(20),
UpColor(green),
DownColor(red);

variables:
MyVol(0),
Color(yellow),
SmoothedBA(0),
Length(squareroot(Period)),
intrabarpersist MyCurrentBar(0),
intrabarpersist VolumeAtBid(0),
intrabarpersist VolumeAtAsk(0),
intrabarpersist BAVolRatio(0),
intrabarpersist VolTmp(0);

if LastBarOnChart then begin
MyVol = Iff(BarType < 2, Ticks, Volume);
if CurrentBar > MyCurrentBar then begin
VolumeAtBid = 0;
VolumeAtAsk = 0;
BAVolRatio = 0;
VolTmp = 0;
MyCurrentBar = CurrentBar;
end;
if InsideBid < InsideAsk then begin
if Close <= InsideBid then
VolumeAtBid = VolumeAtBid + MyVol - VolTmp
else if Close >= InsideAsk then
VolumeAtAsk = VolumeAtAsk + MyVol - VolTmp ;
end;

Hello,

Welcome to the NinjaTrader support forums:

It is difficult for me to understand you, howevere I think I understand what your looking for.

1) This depends on how you run the code. When you start a strategy you choose if you want it to be Calculate on Bar Close = True or Calculate On Bar Close = False.

2) You would want to use the following function:

Let me know if I can be of further assistance.

Hello, thanks for your response.
The second part already is clear, also I have found an indicator which already brings the ninja named buysellpressure that is like.
As regards the first question I understand what I said but I have a doubt.
Do as I do so variables work on Bar Close = True and other Bar Close on = False?
If said me some code example I study and ask you if I have any questions.

Trying to programming this indicator has arisen me another question, in order to use the math class I have to enable it somehow?
I try to use it, but it gives me error, does not exist in the current context.

Sorry my bad English.

If you would like to combine both CalculateOnBarClose settings in one code, please study this sample here - http://www.ninjatrader.com/support/f...ad.php?t=19387

The Math class should be available if you're using the System namespace in your script (which would be the case per default).
